    Some idle questions:

    1. What is the length of daytime -- time between sunrise and sunset -- for
    someone living on the equator?

    2. Does it stay precisely the same year round?

    3. Is the length of daylight slightly perturbed by the revolving of the
    earth around the sun?

    I would guess that daytime at the equator is about 12 hours year round but
    is actually a couple of minutes longer than 12 hours because of the
    earth's orbital travel.

    What do the experts say?
